Rose plant named ‘Evera209’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Evera209’, characterized by its upright and mounding plant habit; dark green-colored leaflets; fragrant double white-colored flowers; flowers held upright on strong and erect peduncles; and good postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘EVERA209’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Roseplant, botanically known as Rosa hybrida, commercially used as a pottedRose, and hereinafter referred to by the name ‘Evera209’.

The new Rose plant is a product of a planned breeding program conductedby the Inventor in Fåborg, Denmark. The objective of the breedingprogram was to develop new uniform potted Rose varieties with novel andattractive flower colors, disease resistance and excellentpostproduction longevity.

The new Rose plant originated from a cross-pollination made by theInventor in October, 2005 of two unnamed proprietary Rose selections,not patented. The new Rose plant was discovered and selected by theInventor in November, 2006 as a single flowering plant within theprogeny of the stated cross-pollination in a controlled greenhouseenvironment in Fåborg, Denmark.

Asexual reproduction of the new Rose plant by cuttings in a controlledgreenhouse environment at Fåborg, Denmark since September, 2008, hasshown that the unique features of this new Rose plant are stable andreproduced true to type in successive generations of asexualreproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Evera209’. These characteristics incombination distinguish ‘Evera209’ as a new and distinct cultivar ofRose:

-   -   1. Upright and mounding plant habit.    -   2. Dark green-colored leaflets.    -   3. Fragrant double white-colored flowers.    -   4. Flowers held upright on strong and erect peduncles.    -   5. Good postproduction longevity.

Plants of the new Rose differ from plants of the parent selections ingrowth habit as plants of the new Rose are more uniform than plants ofthe parent selections.

Plants of the new Rose can be compared to plants of the Rose ‘Evera104’, disclosed in U.S. Plant Pat. No. 16,846. In side-by-sidecomparisons conducted in Fåborg, Denmark, plants of the new Rosediffered from plants of ‘Evera 104’ in the following characteristics:

-   -   1. Plants of the new Rose were fragrant whereas plants of ‘Evera        104’ were not fragrant.    -   2. Plants of the new Rose had larger flowers than plants of        ‘Evera 104’.    -   3. Flowers of plants of the new Rose had more petals than        flowers of plants of ‘Evera 104’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Rose plant, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Rose plant.

The photograph on the first sheet comprises a side perspective view of atypical plant of ‘Evera209’ grown in a container.

The photograph on the second sheet is a close-up view of a typicalflower of ‘Evera209’.

The photograph on the third sheet is a close-up view of the uppersurface of a typical leaf, the lower surface of a typical leaf and atypical flower bud (bottom to top).

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensity,without, however, any variance in genotype. The aforementionedphotographs, following observations and measurements describe plantsgrown during the spring in Sabro, Denmark, in a glass-covered greenhouseand under commercial potted Rose production practices. Plants were grownin 10-cm containers, pinched two times and were nine to twelve weeks oldwhen the photographs and description were taken. During the productionof the plants, day temperatures averaged 21° C., night temperaturesaveraged 19° C. and light levels ranged from 8,000 to 10,000 lux. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, 2007 Edition, except where generalterms of ordinary dictionary significance are used.
